The Hermetic Libraryelaborated on my post, filling in many gaps. Thanks to them I learned that Nema is still around, and her writings are to be found in a number of places. While not from Chicago, her writings influenced the OAI, and will no doubt be of interest to many readers here. She authored the book Maat Magic, A Guide to Self Initiation, which was published by Weiser.

An interview with Nema on the now defunct Thelema Coast to Coast podcast. I am about to listen to this so can't fully comment, but it appears that her portion is a small bit of a much larger show.http://hermetic.com/tctc/archives/31
